n8n - Task runners (`n8nio/runners`) - (PREVIEW)

n8nio/runners image includes JavaScript runner, Python runner and Task runner launcher that connects to a Task Broker running on the main n8n instance when running in external mode. This image is to be launched as a sidecar container to the main n8n container.

Task runners are used to execute user-provided code in the Code Node, isolated from the n8n instance.
